Peanut allergy
Peanut allergy is a type of food allergy distinct from nut allergies. It is a hypersensitivity to dietary substances from peanuts causing an overreaction of the immune system which in a small percentage of people may lead to severe physical symptoms. It is estimated to affect 0.4-0.6% of the population.[1] It is usually treated with an exclusion diet and vigilant avoidance of foods that may be contaminated with whole peanuts or peanut particles and/or oils. The most severe peanut allergies can result in anaphylaxis,[2] an emergency situation requiring immediate attention and treatment with epinephrine.
